The Yaqin MC-13S is a stereo integrated push-pull tube amplifier rated at 40 watts per channel into 8 ohms. It uses four EL34B/6CA7 output tubes, two 12AX7B input/driver tubes, and two 12AU7 tubes. Features include an analog front-panel VU meter, four selectable line-level inputs, 4- and 8-ohm speaker outputs, and ultra-linear output-transformer operation. Published specifications include a frequency response of 10Hz–76kHz, total harmonic distortion of approximately 0.9%, and a signal-to-noise ratio of at least 85dB. The output transformers are specified as using Japanese silicon-steel laminations and enameled wire. Tube and component specifications may vary slightly by production version.
